All --
For those new to the list, I manage an internet marketing
program at a local software startup, Telogy Networks.
Back in April the Netpreneur/AM discussion list was very
helpful to me in working on a solution to a knotty little
problem I was foreseeing in preparing a permission-based
email broadcast list.
The list's goals are:
- to help establish Telogy as a leader
- increased visibility of the company/product name
- promote useful feedback from participants
- get leads/promote sales
The problem was to develop content that was interesting
and relevant to both Technical Product Managers and also
to the engineering community. We have a lot of both on
the list; it is an interesting mix in that there are
substantial differences in their worlds, yet also a great
deal of overlap.
The results were great; I got a bunch of helpful responses.
A summary of my conclusions is avalable in the AM archives,
at:
<http://netpreneur.org/ad-marketing/oldarchives/msg00323.html>
Anyway, after a lengthy content gathering process, the first
edition just went out to 111 willing recipients, and I wanted
to share it with the group. You will see it below.
PLEASE feel free to comment. Your feedback is what helped me
craft this in the first place, additional comments can only
help.
Once again, thanks to all who helped with this, and to those
who work to provide this valuable forum.

I. CHANNEL DENSITY AND MULTI-CHANNEL CAPABILITIES IN
VoIP AND FoIP IMPLEMENTATIONS
When evaluating and implementing voice and fax over IP
(VoIP, FoIP) embedded software solutions, CHANNEL
DENSITY and MULTI-FUNCTION CAPABILITY are important
elements of a complete, integrated solution.
CHANNEL DENSITY
Channel density refers to the number of simultaneous voice
channels (traditional analog lines) or DS0s(64 kbps digital
channels) that can be handled by a single Digital Signal
Processor (DSP). Multi-channel capability is important
for optimizing the overall VoIP implementation.
Why is this so important? Channel density directly affects
implementation costs by determining how many DSPs are
required, how much board level real estate is necessary
and how much power is dissipated. The higher the density,
the lower the solution cost.
However in evaluating channel densities it must be assured
that quality is maintained as higher densities are achieved.
During the development process, engineers are monitoring:
* Is the overall quality of each call maintained as
additional channel processing is added to the DSP?
* What processing capabilities are included for each
channel? Functions such as voice activity detection,
tone detection, playout buffering, jitter buffer
management and echo cancellation are necessary for a
quality voice/fax processing solution.
Many basic developmental areas are involved in maximizing
channel density without sacrificing quality: software
implementation techniques, software architecture,
the algorithm optimization approach and DSP operating
system minimization all play key roles in achieving higher
channel/DSP densities.
MULTI-FUNCTION CAPABILITY
Another important feature in embedded software solutions
for VoIP implementations is a multi-function per channel
capability.
"Multi-function" refers to the ability of the embedded
processing software to detect non-voice activity and
process it accordingly. Many implementations that
offer voice, fax and modem capability require that
the software solution support one function or the
other, or require dedicated DSPs per function.
True multi-function solutions treat and process each
channel as a voice channel. It contains processing
capability to continually monitor and recognize fax
and/or data modem tones and process such calls accordingly,
in real time. To invoke this feature, advanced DSP
processing is required to load and execute fax and
modem software in real time, without disabling any
of the other currently functioning DSP processes.
Like channel density, multi-function capability offers
customers lower development and product costs since
they do not have to provide additional hardware to
support several calls.
And, (like channel density) the multi-function capability
must come with no degradation of quality with multiple calls.
Telogy's Golden Gateway software provides customer
products with multi-channel (4 channels per DSP),
multi-function (voice and fax) capabilities.
